Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to a suction grill used in, for example, a ceiling-mounted air conditioner.

[Technical background of the invention]

In general, ceiling-mounted air conditioners are
There is one shown in the figure.

1 is an indoor unit, which is installed on the ceiling surface of the room. An air suction port is formed on the lower surface of the indoor unit 1, and a suction grill 2 is provided at the air suction port. In addition, indoor unit 1
An air outlet is formed on the side surface of the air outlet, and an outlet grille 3 is provided at the air outlet.

As shown in FIG. 6, the suction grill 2 includes a frame 3, a plurality of gratings 4 arranged integrally on the lower opening surface of the frame 3, and a side of the frame 3 along the arrangement direction of each grating 4. It consists of a filter guide plate 5 provided on the side, a flexible filter 6 inserted between each grid 4 and the filter guide plate 5 from the side side along the grid direction of the frame.

[Problems with background technology]

By the way, in such a suction grill, the frame 3 and the grid 4 are integrally molded from a plastic material, but the filter guide plate 5 is separate from the frame 3 and the grid 4, and is fixed with screws. , speed nut fastening, welding, adhesion (adhesive),
Alternatively, it is attached to the frame 3 by "caulking" or the like. This is because the mounting direction of the filter guide plate 5 is perpendicular to the lattice direction, and in such a situation, the frame 3, the lattice 4,
This is because even if it were attempted to integrally mold all of the filter guide plate 5, mass production would be difficult with current mold technology.

However, the method for attaching the filter guide plate 5 as described above has the problem that the number of parts for attachment increases, leading to an increase in cost and furthermore, a decrease in work efficiency.

[Purpose of invention]

This idea was devised in view of the above circumstances, and its purpose is to easily and reliably attach the filter guide plate to the frame without requiring special parts or troublesome work for attachment. It is an object of the present invention to provide a highly practical suction grill that can reduce costs and improve work efficiency.

[Summary of the idea]

This idea consists of a frame body that is formed by integrally molding multiple gratings and arranged along the opening surface, which is installed at the air inlet of the air conditioner body, and a frame body that is provided on the sides of the frame body along the direction in which each grating is arranged. and a filter inserted between each grid and the filter guide plate from a side side of the frame along the grid direction, and a longitudinal end of the filter guide plate is fitted. grooves to obtain the filter are formed on the sides of the frame along the lattice direction, claws for pressing the surface of the filter guide plate are formed on the sides of the frame along the lattice arrangement direction, and the filter guide A stopper for pressing the side of the plate is formed on the side of the frame along the lattice direction, and a convex portion that engages with the claw is formed on the longitudinal side edge of the filter guide plate. .

[Example of idea]

An embodiment of this invention will be described below with reference to the drawings. However, in the drawings, the same parts as in FIGS. 5 and 6 are designated by the same reference numerals, and detailed explanation thereof will be omitted.

First, in FIG. 4, 20 is a filter guide plate, and this filter guide plate 20 is embedded in the side of the frame 3.

However, as shown in Figures 1 to 3,
In the frame 3, a groove 11 into which one longitudinal end of the filter guide plate 20 can be fitted is formed in the upper part of the side 3a along the lattice direction. Furthermore, in the frame 3, claws 12, 12 for pressing the upper surface of the filter guide plate 20 are formed on the upper edge of the side 3b along the arrangement direction of each grid 4. Further, in the frame body 3, a stopper 1 for pressing the side part of the filter guide plate 20 is provided at the upper part of the side side 3a along the grid direction.
3, 13 is formed. A convex portion 20a is formed on the longitudinal side edge of the filter guide plate 30 to rest on the upper edge of the side edge 3b and engage with the claw portions 12, 12.

Therefore, when attaching the filter guide plate 20 to the frame body 3, it is done as follows.

One longitudinal end of the filter guide plate 20 is connected to the claw portion 1.
2, 12, and in this state, the entire filter guide plate 20 is moved over the stoppers 13, 13 so that the claw portion 1
Insert it below 2,12. When this insertion is completed, the protrusion 20a on the side edge of the filter guide plate 20 fits between the claws 12, 12, rests on the upper edge of the side 3b, and engages with the claws 12, 12. ,
The upper surface of the filter guide plate 20 is pressed by the claws 12, 12, and the filter guide plate 20
The side portions of are held down by stoppers 13, 13.

In this way, the movement of the filter guide plate 20 is restricted in each of the front and rear, left and right, and up and down directions, and the installation is completed.

On the other hand, as shown in FIG. 3, there is a filter insertion part 14 on the side 3a side of the lower opening surface of the frame 3, and when the filter 6 is inserted upward from this filter insertion part 14, The filter 6 is set between the filter guide plate 20 and each grid 4 while slidingly contacting the lower surface of the attached filter guide plate 20.

Moreover, when removing the filter 6, it is sufficient to insert a hand into the filter insertion portion 14 and pull out the filter 6.

In this way, the filter guide plate 20 is attached to the frame body 3 by using the grooves 11 formed in the frame body 3, the claw portions 12, the stoppers 13, and the filter guide plate 20.
Since this is done using the convex portion 20a formed at zero, the filter guide plate 20 can be easily and reliably attached to the frame 3 without requiring special parts for attachment or troublesome work. Therefore, it is possible to reduce costs and improve work efficiency. Moreover, since the filter guide plate 20 can be easily removed from the frame 3 by hand,
Maintenance such as cleaning is easy.

In the above embodiment, the application to a ceiling-mounted air conditioner has been described, but the present invention can also be applied to other air conditioners as long as the air inlet is provided with a suction grill. In addition, it goes without saying that this invention is not limited to the above-mentioned embodiments, and can be modified in various ways without changing the gist.

[Effect of idea]

As described above, according to this invention, there is a frame body formed by integrally molding a plurality of gratings arranged along the opening surface and provided at the air intake port of the air conditioner main body, and an arrangement of each grating of this frame body. a filter guide plate provided on a side along the grid direction; and a filter inserted between each grid and the filter guide plate from the side side of the frame body along the grid direction, Grooves into which the direction ends can be fitted are formed on the sides of the frame along the lattice direction, and claws for pressing the surface of the filter guide plate are formed on the sides of the frame along the lattice arrangement direction. a stopper for pressing a side portion of the filter guide plate is formed on a side of the frame along the lattice direction, and a protrusion that engages with the claw portion on a longitudinal side edge of the filter guide plate; The filter guide plate can be easily and securely attached to the frame body without the need for special mounting parts or troublesome work, thereby reducing costs and improving work efficiency. A highly practical suction grill can be provided.
